Whakaahuatanga o ngā Pereki Whakamarumaru Hiraka
Ko te pereki whakamarumaru hiraka māmā he mea whakamahi i te konganuku hiraka tapatapahi rawa hei rauemi mata. Ko te rahi matūriki matua kāore e neke atu i te 1mm, ā, ko te rahi matūriki neke atu i te 90% he iti iho i te 0.5mm. Ka hangaia te pereki whakamarumaru hiraka mā te tāpiri i te matū mura ki te taumaha, mā te whakamahi rānei i te tikanga mirumiru hau hei hanga hanganga pūngoi mā te tahu, ka taea hoki te hanga i ngā pereki whakamarumaru hiraka hei hua kāore e tahuna.
Ngā Āhuatanga o te Pereki Whakamarumaru Hiraka Mama
- He pai te kawe wera,
- He iti noa te ngaru toenga,
- Te horonga kaha o te para ātete-waikawa,
- Mama te taumaha, ā, he hoa taiao,
- He ātete pai ki te ru wera,
- Te pāmahana teitei, te pumau o te huringa rōrahi,
- He kaha miihini kaha ki te pāmahana teitei.
Te Tukanga Hanga o te Pereki Whakamarumaru Hiraka Mama
Mā te pereki whakamarumaru hiraka māmā ka whakauruhia ngā rauemi mata me te wai ki roto i te taputapu pokepoke kia rite ki tētahi ōwehenga, kātahi ka pokepokea hei paru, ka hangaia te paru hei pereki mā te mīhini, mā te ringa tangata rānei e hanga. Kātahi ka whakamarokehia ngā pereki kia iti iho i te 0.5% te toenga o te wai, ka ārai i te whānui o te rōrahi mai i te hurihanga tioata o te SiO2, ā, ka tahuna ngā pereki kua hangaia ki te pāmahana teitei.
